threonine-type endopeptidase activity
Catalysis of the hydrolysis of internal peptide bonds in a polypeptide chain by a mechanism in which the hydroxyl group of a threonine residue at the active center acts as a nucleophile.
proteasome core complex
A multisubunit barrel shaped endoprotease complex, which is the core of the proteasome complex.
ubiquitin-dependent protein catabolic process
The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein.
